JOHN JUEL, OF LAROI-IVOOD, IOWA.

SELF-FEEDER FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 474,254, dated May 3,1892.

Application filed October 30. 1891. Serial No. 410,342. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN JUEL, a citizen of the United States, and aresident of Larchwood, in the countyof Lyon and Stateof Iowa,haveinvented certain newand useful Improvements in Self- Feeders forThrashing Machines; .and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a side elevation of the invention. Fig. 2 isa vertical longitudinal section. Fig. 3 is a transverse section of thebundle-carrier and partition-board on line y y, and Fig. 4 is a verticaltransverse section on line 00 x.

. This invention has relation to certain new and useful improvements inself-feeders for thrashing machines; and it consists in the novelconstruction and combination of parts, as hereinafter specified.

In the accompanying drawings, the letter A designates a suitable frame,in which is hung an oscillating table B. Journaled in arms a a, securedto the side portions of said frame near its rear end, is a transversecrank-shaft O, 011 the cranks c of which are loosely hung the verticalparallel oscillating arms D D, pivotally and adj ustably connected attheir lower ends to the curved arms or bell-cranks E E. Said arms orbell-cranks are carried by a transverse rock-shaft F underneath thetable and hung in bearings f on the side portions of the frame. Theupper ends ofsaid arms or hellcranks are each provided with a pivot studor journal 6, projecting inwardly therefrom and loosely engagingapertures in lugs or bearingblocks G, secured to the under side of thetable, and thereby forms its oscillating support. This connection givesan oscillating and longitudinally-reciprocatin g movement when thecrank-shaft O is actuated. Said table is preferably of the form shown,having the downwardly-curved rear portion, and transversely ribbed orcorrugated to enable it to more effectually feed the grain to thecylinder of the thrasher. The downward curve of the rear portion of thetable has a tendency to check the too-rapid feed of the bundles underthe cutters and Spreaders, where the grain might become too much jammed,and allows the bundles to become more thoroughly spread over the tablebefore being carried under the cutters and spreaders to the cylinder.

H designates the bundle-carrier, which is pivotally secured at itsforward end to arms h of the frame A at the rear end thereof. Saidcarrieris provided with theendless carrier H, carried by the shafts I Iat the front and rear ends thereof. A longitudinal centralpartition-board K, supported by arms In, secured to the side portions h,divides the bundle-carrier into two longitudinal compartments. The upperportions of the sides h may be hinged to the'lower portions, as shown,so that when not in use they maybe folded into the carrier. The bundlesare discharged onto the rear portion of the oscillating table, Wherethey are engaged by the rotary band-cutters L L. The cutters comprise aseries of sharp-edged circular disks arranged atintervals on thecrankshaft O. Said shaft also carries a series of curved spreaders andfeeders J, arranged between the disks L L. These spreaders or feederscarry the bundles to the cutters, which sever the bands, and the cuttersand spreaderstogether serve to keep the grain disposed straightly andevenly upon the table as it is passed thereunder.

It will be observed that the heavier parts of the machine are attacheddirectly to the separator instead of being secured to the bundlecarrier,which gives them a solid and firm support, and but one oscillatingtableis employed in carrying the grain to the cylinder instead of.two.

In the forward upper end of the guard or hood P of the feeder is arecess 19, which is designed to form a seat for the central longitudinalpartition K of the bundle-carrier when the latter is not in use, saidcarrier by reason of its pivotal connection with the frame A beingadapted to be turned upwardly thereagainst, and obviating the necessityof disconnecting it therefrom when it is desired to move the machine.

The feeder is extremely simple in construction, as will be observed, andis much lighter and more easily driven than those ordinarily in use.

Having described this invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a self-feeder for thrashing-machines, the combination, with theframe having the bundle-carrier connected thereto,of the crankshaftournaled in said frame near the rear end thereof, the oscillatingvertical arms carried by the cranks on said shaft, the bellcranks towhich the lower portions of said arms are connected, said bell-crankshaving ournals thereon, and a corrugatedtable havmg bearings looselyengaged by said journals, sald crank-shaft also carrying aseries of bandcutters and feeders, substantially as specified.

2, In a self-feeder for thrashing-machines, the driving-shaft having thecranks thereon,

and the table oscillating mechanism connected to said cranks, a seriesof rotary cutters also carried on said shaft, and a series of curvedspreader and feeder arms carried by said shaft between said cutters,substantially as specified.

3. The combination,with the frame having the feed-table thereon and thehood or guard arranged over said table and formed with a recess at itsrear portion, of the bundle-carrier hinged to said frame and having acentral longitudinal vertical partition adapted when the carrier isfolded up against the frame to rest in the recess in said hood or guard,

substantially as specified.

4. In a self-feeder for thrashing-machines, the combination, with theframe, of the oscillating feed-table supported thereon, said feedtablebeing transversely corrugated through-' out its length and curveddownward at its rear portion, substantially as specified.

5. The combination, with the feed-table, formed with a series ofcontinuous transverse corrugations and bent downwardly at its rear JOHNJ UEL.
